In 'Unstoppable,' Dawson co-stars with Pine, who portrayed James T. Kirk in the 'Star Trek' reboot. She describes herself as an "uber-Trekkie," but said she hid that fact from Pine. "He didn't find out until we were doing press for the movie that I was a Trekkie," she said. "He goes, 'How did you hide that from me this whole time?' [I said,] 'I didn't want to geek out on you.'"

Dawson remembered an intimate scene with Norton in '25th Hour' that got particularly uncomfortable. "I have to say it was pretty awkward when his girlfriend at the time, Salma Hayek, showed up on set [while] we're doing the bathtub scene," she said.

Dawson also said she had a physical scene on a rooftop with Downey in 'A Guide to Recognizing Your Saints' that may have gone a bit too far. "So, I get into this scene and I, like, knock him on his forehead," she said. "And his eyes broke character. It was, like, 'Do not touch my face.' I was, like, 'Oh my God, I'm going to get thrown off the roof right now.'"
